I've been gifted with a PDP-11/53 (or 53+) CPU module.
The CPU is from a DECserver 550, and I have the box as
well, so I'll be able to build up my PDP-11 there rather
than use my BA23 from my MVII. From what I've been able
to determine the CPU modules in the DECserver 550 has
different ROMs, so I'll need to replace them to make
a bootable system. I'll be able to use the Ethernet
card in the DECserver 550 (DELQA), and I'll move over
my RQDX3 and RD54 drives from the MVII. Since the
CPU has 1.5M of RAM I won't need any extra memory
(and from reading the PDP-11 history, adding memory
off-board adds a real performance hit.
So, does any here have a source for bootable ROMs
for this CPU?

I just heard from someone a few minutes ago, that if you've got a 3rd party
disk controller that you can boot the system off you should be able to
simply remove the ROM's.

For all of you who have been able to enjoy it, the word is...
Wet.
I managed to pick up a Thinkpad 360C with a cracked hinge for $20 and a
docking station for it for $5 (locked with no key, but it took 5 minutes
to disassemble the lock via the ISA slot). Other notables include a free
Silent 700 (from the same guy who gave me that pile of Atari 800 stuff
a few weeks ago) and a copy of "The Lost Treasures of Infocom" on floppy
(with maps and books) for $5.
Dayton is more fun when it's dry, but it's even fun on a day like today.
It's just indoor fun.

I was able to hit the Hamvention myself today. The item of the day was
definitely the 486 laptop. I saw tons of these, as well as its close
cousin, the 386 laptop.
Not a lot of great classic hardware around, but I did see many older
Sparcstation boxes. Also of interest was an SGI Indigo Iris (passed on it
at $75) and an Apple II made especially for Bell & Howell with drive (also
passed, $350!). I did pick up a nice Commodore drive -- the MSD SD-2, $20.
All in all it was a good time, though. I just like looking at all that old
stuff and wondering what the heck it does! :)

Most were waaaay overpriced.

Sparcstation boxes.
I didn't get around enough in the rain to see any, which is a shame, because
my SPARC-LX died in a recent thunderstorm (SCSI controller flaked out) and I
had to replace it with a SPARC-Classic I fortunately picked up at the local
University surplus recently for $5 (16Mb RAM, no disk). I did see one guy who
got a pair of SPARC-5s for $175. I'd've bought them if I'd gotten there
first.
I'm casually looking for something in a sun4m or sun4u for <$500.
Also of interest... an Apple II made especially for
Bell & Howell with drive
(also passed, $350!).
Saw that. Gawked, laughed and passed on...
I did pick up a nice Commodore drive -- the MSD SD-2,
$20.
Saw that, too. Decided I didn't need it as much as I needed the money.
All in all it was a good time, though. I just like

stuff and wondering what the heck it does! :)
That's my favorite part. I just wish I had been able to spend more time
this weekend there. I had to cut my time short for a pressing engagement
elsewhere. :-(

An interrim solution is to use an other computer with a scriptable
terminal emulator like kermit or minicoma as console. With this setup
you can run a script that feeds an bootstrap code via ODT into RAM. I
own a PDP11/73 with MSCP ESDI adapter + 150MB disk, TK50, DELQA, DHV11
and 4MB RAM but no boot ROM card. I use a minicom script to boot
2.11BSD. This works fine. Bootstraps can be found on various sites on
the net, convertig it to a script is just a bit of sed/awk. Or ask me
for my minicon script. :-)
